Description

Technical Field

[0001] The present application relates to the technical field of stamping dies, and particularly relates to a multi-item isothermal stamping die, a processing method, a system, and a storage medium for a heating tube thereof. Background Art

[0002] A stamping die is a processing tool widely used in industrial production. During the stamping process, temperature control of the die is crucial. Especially for the isothermal stamping process, the uniformity and stability of the die temperature directly affect the forming quality and accuracy of the product. A stamping die usually includes a die base, and the die base includes an upper die base, a lower die base, a left die base, and a right die base. The left die base and the right die base move closer to clamp the product, and then the upper die base moves downward to press the left die base and the right die base to prevent the left die base and the right die base from moving. A plurality of heating tubes are arranged in the left die base and the right die base. After the heating tubes are energized and generate heat, the heat is transferred to the left die group and the right die group through heat exchange, so that the left die base and the right die base are heated and raised in temperature, thereby heating and shaping the product.

[0003] In view of the above related technologies, during the heating process, there is a probability that the heating tubes are in poor contact with the die base, resulting in the heat of the heating tubes not being transferred to the die base well, or there is a probability that the heating tubes themselves have faults, resulting in insufficient heat generation. This causes uneven heating of the die base, resulting in uneven heating of the product during heating and forming, and affecting the forming quality and accuracy of the product. Summary of the Invention

[0004] In order to provide stable and uniform heat to the die base, the present application provides a multi-item isothermal stamping die, a processing method, a system, and a storage medium for a heating tube thereof.

[0005] In a first aspect, the present application provides a processing method for a heating tube of a multi-item isothermal stamping die, adopting the following technical solution: A processing method for a heating tube of a multi-item isothermal stamping die includes: Sequentially detecting the current values of the connection wires connecting a plurality of heating tubes; Grouping the current values that are not less than the current threshold among all the current values according to a preset rule to form N data sets; Subtracting the current value in each data set from the average value of the corresponding data set to obtain a deviation value; Judging whether there is a deviation value greater than a preset deviation value; If so, marking the connection wire corresponding to the current value with the deviation value greater than the preset deviation value as a target wire; In the case where the difference between the voltage at both ends of the heating tube corresponding to the target wire and a preset voltage is greater than a preset voltage difference, marking the heating tube corresponding to the target wire as a target heating tube; Control the target heating tube according to a preset control method.

[0006] By adopting the above technical solution, when the heating tube is working, the current value of the heating tube is detected in sequence, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault on this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, this heating tube is marked as the target heating tube and is controlled by a preset control method to control the target heating tube, so as to provide stable and uniform heat for the die holder.

[0007] Optionally, the step of controlling the target heating tube according to a preset control method includes: Obtain the temperature data of several detection points in the target heating tube according to a preset detection sequence; Define the detection points with the temperature data greater than the temperature upper limit threshold or less than the temperature lower limit threshold as temperature abnormal points; Judge whether the number of the temperature abnormal points is greater than the preset upper limit number; If so, when the temperature data of the temperature abnormal points is less than the temperature lower limit threshold, increase the power of the target heating tube to the preset power; If not, judge whether the number of the temperature abnormal points is less than the preset lower limit number; If so, execute the heating tube control step, and the heating tube control step includes: when the temperature data of the temperature abnormal points is less than the temperature lower limit threshold, control the position of the target heating tube in the die holder according to the first control method; when the temperature data of the temperature abnormal points is greater than the temperature upper limit threshold, control the position of the target heating tube in the die holder according to the second control method.

[0008] By adopting the above technical solution, by obtaining the temperature data of the detection point, it is possible to determine whether the detection point is a temperature abnormal point according to the temperature data. When the number of temperature abnormal points is greater than the preset upper limit number, and the temperature data of the temperature abnormal points is less than the temperature lower threshold, the power of the heating tube is increased to the preset power to improve the insufficient heat generation situation. When the number of temperature abnormal points is less than the preset lower limit number, it indicates that there is a situation of insufficient temperature or local overheating in the heating tube. Therefore, when the temperature data of the abnormal point is less than the temperature upper threshold, the position of the target heating tube in the die holder is controlled according to the first control method to improve the situation of insufficient local temperature of the heating tube; when the temperature data of the abnormal point is greater than the temperature upper threshold, the position of the target heating tube in the die holder is controlled according to the second control method, and the local overheating situation of the heating tube is improved through the heat exchange principle.

[0009] Optionally, the step of controlling the position of the target heating tube in the die holder according to the first control method includes: Obtain the first position information of the temperature abnormal point on the target heating tube; Calculate the first interval length occupied by the temperature abnormal point on the target heating tube according to the first position information; Reciprocally move the position of the target heating tube in the die holder according to the first interval length and at a first preset frequency.

[0010] By adopting the above technical solution, when there is local insufficient temperature in the target heating tube, by obtaining the first position information of the temperature abnormal point on the target heating tube, and obtaining the first interval length according to the first position information, that is, the length of the local insufficient heat generation part, the position of the target heating tube in the die holder is reciprocally moved according to the first interval length, so that the heat generation area of the target heating tube can transfer heat to the die holder according to the heat exchange principle to heat the corresponding die holder part of the insufficient temperature part, so as to make up for the situation of local insufficient temperature of the target heating tube.

[0011] Optionally, the step of controlling the position of the target heating tube in the die holder according to the second method includes: Obtain the second position information of the temperature abnormal point on the target heating tube; Calculate the second interval length occupied by the temperature abnormal point on the target heating tube according to the second position information; Judge whether the second interval length is less than the bottom perimeter of the target heating tube; If so, reciprocally move the position of the target heating tube in the die holder according to the second interval length and at a second preset frequency; If not, rotate the target heating tube according to the preset rotation frequency to uniformly heat the mold.

[0012] By adopting the above technical solution, when the target heating tube has a local bend, heat cannot be transferred well into the die holder, resulting in a local temperature deficiency in the die holder while the target heating tube has a local overheating condition. Therefore, the second position information of the temperature anomaly point is obtained, and the second interval length is calculated based on the second position information. When the second interval length is less than the bottom perimeter of the target heating tube, the target heating tube is reciprocally moved to transfer heat to the area with insufficient temperature in the die holder in the form of heat exchange; when the second interval length is greater than the bottom perimeter of the target heating tube, the target heating tube is rotated at a preset rotation frequency so that the side of the local bend area in contact with the die holder can heat the area of the die holder corresponding to the non-contact side, thereby improving the situation of local temperature deficiency in the die holder.

[0013] Optionally, the step of calculating the second interval length occupied by the temperature anomaly point on the target heating tube according to the second position information includes: Form a scatter plot based on the second position information of the detection points and the temperature data, and fit the scatter plot to obtain a curve graph; Intersect the curve graph with a preset temperature line to obtain a first intersection point and a second intersection point; Extract the abscissas of the first intersection point and the second intersection point to obtain a first abscissa and a second abscissa; Obtain the second interval length by calculating the absolute value of the difference between the first abscissa and the second abscissa.

[0014] By adopting the above technical solution, a scatter plot is formed based on the second position information and the temperature data, and the scatter plot is fitted to obtain a curve graph, which can reflect the change trend of the temperature of the target heating tube along the length direction through the curve graph. By intersecting the curve graph with a preset temperature line to obtain a first intersection point and a second intersection point, the second interval length can be obtained more accurately.

[0015] Optionally, when the current value of the connection wire is less than the current threshold, mark the heating tube corresponding to the connection wire as a problematic heating tube; Mark the heating tubes within a preset distance range from the problematic heating tube among several heating tubes as temporary heating tubes; Successively increase the power of the temporary heating tubes according to a preset order.

[0016] By adopting the above technical solution, when the current value of the connecting wire is less than the current threshold, it indicates that the circuit corresponding to the connecting wire is open, that is, the heating tube corresponding to the connecting wire is not working properly, and the heating tube is marked as a problematic heating tube. Then, the heating tubes among several heating tubes whose distances from the problematic heating tube are within the preset distance range are marked as temporary heating tubes. By sequentially increasing the power of the temporary heating tubes in a preset order, the heat missing due to the non - normal operation of the problematic heating tube can be compensated, so that the overall heat of the die base is stable.

[0017] Optionally, the step of sequentially increasing the power of the temporary heating tubes according to a preset order includes: Obtain the distance data of each of the temporary heating tubes to the problematic heating tube; Form a distance data set according to the distance data in ascending order; Determine a preset duration according to the distance data in the distance data set and a preset coefficient; Execute the power - increasing step, and the power - increasing step includes: increasing the power of the temporary heating tube according to the order of the distance data in the distance data set until reaching the corresponding preset duration; Repeat the power - increasing step until the die heating ends.

[0018] By adopting the above technical solution, by sequentially increasing the power of the temporary heating tube to reach the preset duration, temperature compensation can be performed on the die base where the problematic heating tube is located in the form of heat exchange through the temporary heating tube, so as to prevent uneven heating of the die base.

[0019] In a second aspect, the present application provides a heating tube processing system for a multi - item isothermal stamping die, adopting the following technical solution: A heating tube processing system for a multi - item isothermal stamping die includes an acquisition module for acquiring current values, temperature data, first position information, second position information, and distance data; A memory for storing a program of the heating tube processing method for the multi - item isothermal stamping die; A processor, and the program in the memory can be loaded and executed by the processor to implement the heating tube processing method for the multi - item isothermal stamping die.

[0020] By adopting the above technical solution, when the heating tube is working, the current values of the heating tube are sequentially detected, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, this heating tube is marked as the target heating tube and the target heating tube is controlled by a preset control method, so as to provide stable and uniform heat for the die base.

[0021] In a third aspect, the present application provides a multi-item isothermal stamping die, adopting the following technical solution: A multi-item isothermal stamping die includes a power control cabinet, and the power control cabinet includes a memory and a processor. A computer program capable of being loaded and executed by the processor for any one of the above methods is stored on the memory.

[0022] In a fourth aspect, the present application provides a computer storage medium, which can store corresponding programs and has the characteristic of being convenient for providing stable heat for the die base, adopting the following technical solution: A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor for the heating tube processing method of any one of the above multi-item isothermal stamping dies.

[0023] By adopting the above technical solution, when the heating tube is working, the current values of the heating tube are sequentially detected, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, this heating tube is marked as the target heating tube and the target heating tube is controlled by a preset control method, so as to provide stable and uniform heat for the die base.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: When the heating tube is working, the current value of the heating tube is detected in sequence, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By determining whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is too low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may be faulty. Therefore, this heating tube is marked as the target heating tube and the target heating tube is controlled by a preset control method to provide stable and uniform heat for the die base; When the target heating tube is locally bent, the heat cannot be transferred well into the die base, resulting in local insufficient temperature in the die base while the target heating tube is locally overheated. Therefore, the second position information of the temperature anomaly point is obtained, and the second interval length is calculated based on the second position information. When the second interval length is less than the bottom circumference of the target heating tube, the target heating tube is reciprocally moved to transfer heat to the area with insufficient temperature in the die base in the form of heat exchange; when the second interval length is greater than the bottom circumference of the target heating tube, the target heating tube is rotated at a preset selection frequency so that the side of the locally bent area in contact with the die base can heat the die base area corresponding to the non-contact side to improve the situation of local insufficient temperature in the die base; By sequentially increasing the power of the temporary heating tube to reach the preset duration, heat compensation can be performed on the die base where the problematic heating tube is located through the temporary heating tube in the form of heat exchange to prevent uneven heating of the die base.

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer, the following Figure 1-8 are further described in detail in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a multi-item isothermal stamping die. Referring to Figure 1 , the multi-item isothermal stamping die includes a die base 1, a relay cabinet 2 connected to the die base 1, and a power control cabinet 3 connected to the relay cabinet. The die base 1 includes a left die base 11 and a right die base (only the left die base 11 is shown in the figure, and the right die base is located on the back side of the left die base 11). A plurality of heating pipes 12 are arranged in both the left die base 11 and the right die base. The heating pipes are connected to the relay cabinet 2 and the power control cabinet 3 through connecting wires 4.

[0036] The embodiment of the present application discloses a heating pipe processing method for a multi-item isothermal stamping die. Referring to Figure 2 , the heating pipe processing method includes: Step S201: Sequentially detect the current values of the connecting wires connecting a plurality of heating pipes.

[0037] The heating pipe is a tube body that can generate heat and is in a long cylindrical shape. Heating holes for inserting the heating pipes are provided in both the left die base and the right die base. The heating pipes are inserted into the heating holes, and the heating pipes generate heat and transfer the heat to the left die base and the right die base through heat exchange.

[0038] The connecting wire is a wire connecting the heating pipes.

[0039] Exemplarily, the total number of heating pipes is 20. Among them, there are 10 heating pipes on the left die base and 10 heating pipes on the right die base. By sequentially measuring the current values on the connecting wires, it is possible to judge whether there is a fault in the corresponding circuit according to the current values.

[0040] Step S202: Group the current values that are not less than the current threshold among all the current values according to a preset rule to form N data sets.

[0041] The current threshold is a preset constant and can be adjusted according to actual requirements. On the other hand, when the current value passing through the connecting wire is less than the current threshold, it means that there may be an open circuit in the circuit.

[0042] The preset rule is used to group the current values corresponding to several connecting wires.

[0043] A data set is a set obtained by grouping current values according to a preset rule.

[0044] Exemplarily, among 20 connecting wires, there is no connecting wire with a current value less than the current threshold. Randomly and evenly divide the 20 current values into 4 groups to form 4 data sets. Therefore, N takes the value of 4, and each data set has 5 current values.

[0045] Exemplarily, among 20 connecting wires, if there is 1 connecting wire whose corresponding current value is less than the current threshold, it means that there may be an open circuit in the circuit corresponding to this current value. Therefore, divide the remaining 19 current values into 4 groups to form 4 data sets. Each of 3 data sets contains 5 current values, and the remaining 1 data set contains 4 current values.

[0046] Step S203: Subtract the current value in each data set from the average value of the corresponding data set to obtain a deviation value.

[0047] Exemplarily, among 20 connecting wires, in the case where there is no connecting wire with a current value less than the current threshold, use A, B, C, and D to represent the 4 data sets respectively. Calculate the average values of A, B, C, and D respectively. Then subtract the current value in each data set from the average value of the data set corresponding to this current value to obtain a deviation value. The deviation value represents the degree of deviation between the current value and the average value of the corresponding data set, and whether there is a fault in the circuit corresponding to the connecting wire can be reflected through the deviation value.

[0048] Step S204: Determine whether there is a deviation value greater than a preset deviation value.

[0049] The preset deviation value is a preset constant and can be adjusted according to actual requirements.

[0050] Exemplarily, in data set A, there is a current value a1. The difference between a1 and the average value A1 of A is the deviation value Δa1. Among them, if Δa1 is greater than the preset deviation value ΔA1 of A, that is, Δa1>ΔA1, it means that there is a deviation value greater than the preset deviation value in A.

[0051] Step S205: If so, mark the connecting wire corresponding to the current value with a deviation value greater than the preset deviation value as the target wire.

[0052] In another aspect, if there is no deviation value greater than the preset deviation value, it means that several heating tubes are working properly and no operation is required.

[0053] Among them, when calculating the deviation value of the current value, the deviation value is obtained by subtracting the current value from the average value of the data set corresponding to the current value and taking the absolute value. Therefore, there is a situation where the deviation value obtained after subtracting the average value from the current value is positive and the deviation value is greater than the preset deviation value. Based on this situation, it means that there is a short circuit in the circuit corresponding to the current value. Therefore, it is necessary to turn off this circuit through the power control cabinet. In this embodiment, the deviation value mainly considers the situation where the current value is less than the average value of the data set.

[0054] Exemplarily, if the deviation value Δa1 between the current value a1 in the data set A and the average value A1 is less than the preset deviation value ΔA1, it means that the current value of the connecting wire corresponding to a1 is low, that is, there may be a fault in the circuit where the connecting wire is located. Mark the connecting wire corresponding to the current value a1 as the target wire.

[0055] Step S206: When the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, mark the heating tube corresponding to the target wire as the target heating tube.

[0056] The preset voltage is a preset constant and is related to the voltage at both ends of the heating tube corresponding to the target wire, and can be adjusted according to actual needs.

[0057] The preset voltage difference is a preset constant and can be adjusted according to actual needs.

[0058] By measuring the voltage at both ends of the heating tube corresponding to the target wire, and then comparing the difference between the voltage at both ends of the heating tube and the preset voltage with the preset voltage difference, it is possible to judge whether the fault point in the circuit is caused by this heating tube according to the comparison result.

[0059] When the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it means that there is a fault in the heating tube corresponding to the target wire. Therefore, mark this heating tube as the target heating tube.

[0060] In another aspect, if the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is not greater than the preset voltage difference, it means that there is no fault in the heating tube corresponding to the target wire, and the fault point is between the relay cabinet and the power control cabinet. Therefore, it is necessary to troubleshoot the relay cabinet and the power control cabinet.

[0061] Step S207: Control the target heating tube according to a preset control method.

[0062] In the case where the target heating tube fails, control the target heating tube through a preset control method so as to continuously provide stable heat to the mold base.

[0063] By adopting the above technical solution, when the heating tube is working, the current values of the heating tube are sequentially detected, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may be faulty. Therefore, this heating tube is marked as the target heating tube and the target heating tube is controlled through a preset control method, so as to provide stable and uniform heat for the mold base.

[0064] Refer to Figure 3 , the steps of controlling the target heating tube according to a preset control method include: Step S301: Obtain the temperature data of several detection points in the target heating tube according to a preset detection order.

[0065] Among them, several temperature sensors are evenly spaced along the length of the target heating tube, and the points where the temperature sensors are located are the detection points. Exemplarily, 15 temperature sensors are arranged in the target heating tube, so the number of detection points is 15. The preset detection order is to sequentially obtain the data of the temperature sensors from one end of the target heating tube close to the target wire towards the end of the target heating tube far from the target wire, so as to sequentially obtain the temperature data of the detection points.

[0066] Step S302: Define the detection points with temperature data greater than the temperature upper limit threshold or less than the temperature lower limit threshold as temperature abnormal points.

[0067] The temperature upper limit threshold is a preset constant, which is related to the temperature on the heating tube and can be adjusted according to actual needs.

[0068] The temperature lower limit threshold is a preset constant, which is related to the temperature on the heating tube and can be adjusted according to actual needs.

[0069] When the temperature data is greater than the upper temperature threshold, it indicates that there is an overheating situation at the detection point, that is, there is a local overheating situation in the target heating tube. When the temperature data is less than the lower temperature threshold, it indicates that there is a temperature deficiency at the detection point, that is, there is a local temperature deficiency situation in the target heating tube. The detection points with overheating or temperature deficiency are defined as temperature abnormal points.

[0070] Step S303: Determine whether the number of temperature abnormal points is greater than the preset upper limit number.

[0071] The preset upper limit number is a preset constant, related to the number of temperature abnormal points on the target heating tube, and can be adjusted according to actual needs. Exemplarily, the preset upper limit number can be set to 10.

[0072] By determining whether the number of temperature abnormal points is greater than the preset upper limit number, in the case where the number of temperature abnormal points is greater than the preset upper limit number, step S304 is executed. In the case where the number of temperature abnormal points is not greater than the preset upper limit number, step S305 is executed.

[0073] Step S304: If so, when the temperature data of the temperature abnormal point is less than the lower temperature threshold, increase the power of the target heating tube to the preset power.

[0074] The preset power is a preset constant, related to the power of the heating tube. When the heating tube generates insufficient heat, the heat generation of the heating tube can be increased by increasing the power of the heating tube to the preset power, so as to increase the heat exchange amount with the mold base. The preset power can be adjusted according to actual needs.

[0075] If so, it means that the number of temperature abnormal points is greater than the preset number, indicating that most areas of the target heating tube may have overheating or temperature deficiency. Therefore, when the temperature data of the temperature abnormal point is less than the lower temperature threshold, it means that most areas of the target heating tube have insufficient temperature. At this time, by increasing the power of the target heating tube to the preset power, the heat generation amount can be increased, so as to increase the heat exchange amount with the mold base. If after increasing the power of the target heating tube to the preset power, the temperature data of the temperature abnormal point of the target heating tube is still less than the lower temperature threshold, the target heating tube can be replaced after the heating is completed.

[0076] On the other hand, there may be a certain gap between one side of the target heating tube and the inner wall of the heating hole, making it impossible to transfer the temperature of the target heating tube well, resulting in the temperature data of the temperature abnormal point being greater than the upper temperature threshold. Based on this situation, the target heating tube can be slowly rotated to make the target heating tube heat the mold base evenly.

[0077] Step S305: If not, determine whether the number of temperature abnormal points is less than the preset lower limit number.

[0078] The preset lower limit quantity is a preset constant and can be adjusted according to the actual situation. Exemplarily, the preset lower limit quantity can be set to 5.

[0079] Step S306: If so, execute the step of controlling the heating tube, and the step of controlling the heating tube includes: when the temperature data at the temperature anomaly point is less than the temperature lower limit threshold, controlling the position of the target heating tube in the mold base according to the first control method; when the temperature data at the temperature anomaly point is greater than the temperature upper limit threshold, controlling the position of the target heating tube in the mold base according to the second control method.

[0080] If so, it means that the number of temperature anomaly points is less than the preset lower limit quantity, indicating that there is a situation of local temperature deficiency or local overheating in the heating tube. When the temperature data at the temperature anomaly point is less than the temperature lower limit threshold, it means that there is local temperature deficiency in the target heating tube. At this time, the position of the target heating tube in the mold base is controlled by the first control method, so that the area with normal temperature in the heating tube heats the corresponding mold base area of the temperature-deficient area in the form of heat exchange.

[0081] When the temperature data at the temperature anomaly point is greater than the temperature upper limit threshold, it means that there is a situation of local overheating in the target heating tube. Exemplarily, when the target heating tube has a local bend, the local bend area cannot fit well with the inner wall of the heating hole, resulting in the heat in the local bend area not being able to be transferred to the mold base well. On the one hand, it causes uneven heating of the mold base, and on the other hand, it causes local overheating of the target heating tube. At this time, the position of the target heating tube in the mold base is controlled according to the second control method to heat the mold base evenly.

[0082] On the other hand, if the number of temperature anomaly points is greater than the preset lower limit quantity and less than the preset upper limit quantity, when the temperature data at the temperature anomaly point is less than the temperature lower limit threshold, the power of the target heating tube can be increased by the method of step S304.

[0083] When the temperature data at the temperature anomaly point is greater than the temperature upper limit threshold, based on this situation, exemplarily, the target heating tube has a long-area bend, and the bend area cannot fit well with the inner wall of the heating hole. On the one hand, the heat on the bent side of the target heating tube cannot be transferred to the mold base well, resulting in a long-area overheating situation of the target heating tube. On the other hand, due to the bend area not being able to fit well with the inner wall of the heating hole, the target heating tube cannot exchange heat with the mold base well, resulting in uneven heating of the mold base. The target heating tube can be rotated so that the side of the bend area of the target heating tube that fits with the heating hole can rotate, making the mold base heated evenly. The specific steps can refer to Figure 5 the embodiment.

[0084] By adopting the above technical solution, by obtaining the temperature data of the detection points, it is possible to judge whether it is a temperature abnormal point according to the temperature data. When the number of temperature abnormal points is greater than the preset upper limit number, and the temperature data of the temperature abnormal points is less than the temperature lower limit threshold, the power of the heating tube is increased to the preset power to improve the insufficient heating situation. When the number of temperature abnormal points is less than the preset lower limit number, it indicates that there is a situation of insufficient temperature or local overheating in the heating tube. Therefore, when the temperature data of the abnormal points is less than the temperature upper limit threshold, the position of the target heating tube in the die base is controlled according to the first control method to improve the situation of insufficient local temperature of the heating tube; when the temperature data of the abnormal points is greater than the temperature upper limit threshold, the position of the target heating tube in the die base is controlled according to the second control method, and the principle of heat exchange is used to improve the situation of local overheating of the heating tube.

[0085] Referring to Figure 4 , the steps of controlling the position of the target heating tube in the die base according to the first control method include: Step S401: Obtain the first position information of the temperature abnormal point on the target heating tube.

[0086] The first position information is the information of the position of the temperature abnormal point on the target heating tube when the number of temperature abnormal points is less than the preset lower limit number and the temperature data of the temperature abnormal points is less than the temperature lower limit threshold. Exemplarily, if the temperature data of the 3rd to 5th detection points among the 15 detection points in the target heating tube is less than the temperature lower limit threshold, the information of the positions of the 3rd to 5th detection points on the target heating tube is obtained.

[0087] Step S402: Calculate the first interval length occupied by the temperature abnormal point on the target heating tube according to the first position information.

[0088] The first interval length is the interval length occupied by all temperature abnormal points on the target heating tube. Exemplarily, the 3rd to 5th detection points among the 15 detection points in the target heating tube are temperature abnormal points. Since the temperature sensors are evenly spaced along the length direction in the target heating tube, the first interval length is the corresponding distance length between the 3rd temperature sensor and the 5th temperature sensor, that is, the corresponding distance length between the 3rd detection point and the 5th detection point. Among them, the acquisition method of the first interval length can refer to Figure 6 Embodiment.

[0089] Step S403: Reciprocally move the position of the target heating tube in the die base according to the first interval length and at the first preset frequency.

[0090] The first preset frequency is a preset constant, indicating the frequency of moving the target heating tube, and can be adjusted according to actual needs.

[0091] Exemplarily, the temperature data from the 3rd temperature anomaly point to the 5th temperature anomaly point is less than the lower temperature threshold. According to the first interval length, the position of the target heating tube in the die holder can be reciprocally moved, and the moving length each time is at least half of the first interval length. The first preset frequency can be to move the target heating tube once every 5 seconds, so that the part of the heating tube except for the 3rd temperature anomaly point to the 5th temperature anomaly point can perform heat exchange on the area of the die holder corresponding to the 3rd temperature anomaly point to the 5th temperature anomaly point to heat the die holder.

[0092] By adopting the above technical solution, when there is local insufficient temperature in the target heating tube, by obtaining the first position information of the temperature anomaly point on the target heating tube, and obtaining the first interval length according to the first position information, that is, the length of the locally insufficient heating part, the position of the target heating tube in the die holder is reciprocally moved according to the first interval length, so that the heating area of the target heating tube can transfer heat to the die holder according to the heat exchange principle to heat the die holder corresponding to the temperature insufficient part, so as to make up for the situation of local insufficient temperature in the target heating tube.

[0093] Refer to Figure 5 , the steps of controlling the position of the target heating tube in the die holder according to the second method include: Step S501: Obtain the second position information of the temperature anomaly point on the target heating tube.

[0094] The second position information is the information of the position of the temperature anomaly point on the target heating tube when the number of temperature anomaly points is less than the preset lower limit number and the temperature data of the temperature anomaly point is greater than the upper temperature threshold. When the target heating tube has local bending and the bending area cannot fit well with the inner wall of the heating hole, on the one hand, it makes the target heating tube unable to perform heat exchange well with the die holder on the bending side, so that the temperature of the target heating tube cannot be transferred to the die holder well, resulting in a higher temperature in the bending area of the target heating tube. On the other hand, the temperature on the bending side of the target heating tube cannot be transferred to the die holder well, resulting in uneven heating of the die holder.

[0095] Exemplarily, if the temperature data from the 7th detection point to the 9th detection point among the 15 detection points in the target heating tube is greater than the upper temperature threshold, then obtain the position information of the 7th detection point to the 9th detection point on the target heating tube, that is, the position information of the temperature anomaly point on the target heating tube, and the area corresponding to the 7th detection point to the 9th detection point on the target heating tube is the bending area of the target heating tube.

[0096] Step S502: Calculate the second interval length occupied by the temperature anomaly point on the target heating tube according to the second position information.

[0097] The length of the second interval is the length of the interval occupied by all temperature anomaly points on the target heating tube. Exemplarily, the 7th to 9th detection points among the 15 detection points in the target heating tube are temperature anomaly points, and the temperature sensors are evenly spaced along the length direction in the target heating tube. Therefore, the length of the second interval is the corresponding distance length between the 7th temperature sensor and the 9th temperature sensor, that is, the corresponding distance length between the 7th detection point and the 9th detection point.

[0098] Step S503: Determine whether the length of the second interval is less than the bottom circumference of the target heating tube.

[0099] By comparing the length of the second interval with the bottom circumference of the target heating tube, if the length of the second interval is less than the bottom circumference of the target heating tube, then step S504 is executed; if the length of the second interval is not less than the bottom circumference of the target heating tube, then step S505 is executed.

[0100] Step S504: If so, reciprocally move the position of the target heating tube in the mold base according to the length of the second interval and at a second preset frequency.

[0101] The second preset frequency is a preset frequency, indicating the frequency of moving the target heating tube, which can be adjusted according to actual needs.

[0102] If so, it means that the length of the second interval is less than the bottom circumference of the target heating tube. By reciprocally moving the position of the target heating tube in the mold base at the second preset frequency, the mold base is uniformly heated. The target heating tube can be reciprocally moved by a manipulator. Exemplarily, the 7th to 8th detection points are temperature anomaly points, that is, the area corresponding to the 7th to 8th detection points on the target heating tube is the bending area of the target heating tube, and the length corresponding to the bending area is the length of the second interval. By moving the target heating tube, the target heating tube corresponding to the 1st to 6th detection points and the 9th to 15th detection points can heat the mold base corresponding to the bending area. Among them, the moving distance is at least half of the length of the second interval, the second preset frequency can be moving once every 5 seconds, and the moving time for one time is 5 seconds. Through reciprocal movement, heat exchange is performed on the mold base area corresponding to the bending area, so that the mold base is uniformly heated.

[0103] Step S505: If not, rotate the target heating tube according to a preset rotation frequency to uniformly heat the mold.

[0104] The preset rotation frequency is a preset constant, related to the frequency of rotating the target heating tube, which can be adjusted according to actual needs.

[0105] If not, it means that the length of the second interval is not less than the bottom circumference of the target heating tube. Exemplarily, the 7th to 9th detection points are temperature anomaly points, the length of the template heating tube corresponding to the 7th to 9th detection points is the length of the second interval, and the length of the second interval is not less than the bottom circumference of the target heating tube. By rotating the target heating tube at a preset rotation frequency, the bent area can be rotated in the heating hole, so that the side of the bent area that fits the heating hole can rotate to perform heat exchange on the mold base, so as to avoid the problem that the side of the bent area that cannot fit the inner wall of the heating hole always stays in the same position, resulting in a relatively low temperature of the mold base corresponding to this position.

[0106] By adopting the above technical solution, when the target heating tube is locally bent, heat cannot be transferred well to the mold base, resulting in local temperature deficiency in the mold base, while the target heating tube has a local overheating condition. Therefore, the second position information of the temperature anomaly point is obtained, and the length of the second interval is calculated according to the second position information. When the length of the second interval is less than the bottom circumference of the target heating tube, the target heating tube is reciprocally moved to transfer heat to the area with insufficient temperature of the mold base in the form of heat exchange; when the length of the second interval is greater than the bottom circumference of the target heating tube, the target heating tube is rotated at a preset selection frequency, so that the side of the locally bent area that fits the mold base can heat the mold base area corresponding to the non-fitting side, so as to improve the situation of local temperature deficiency in the mold base.

[0107] Refer to Figure 6 , the steps of calculating the length of the second interval occupied by the temperature anomaly point on the target heating tube according to the second position information include: Step S601: Form a scatter plot based on the second position information and temperature data of the detection points, and fit the scatter plot to obtain a curve graph.

[0108] Among them, the relationship between the second position information and temperature data at the current moment is represented by a scatter plot, and the scatter plot is fitted to obtain a curve graph. The distribution law of the second position information and temperature data is intuitively displayed through the curve graph.

[0109] Exemplarily, the second position information is used as the abscissa, and the temperature data is used as the ordinate. The zero point of the abscissa is the end of the target heating tube close to the connecting wire, and the length of the target heating tube is mapped to the abscissa. The position of the temperature sensor on the target heating tube can be reflected by the abscissa, that is, the position corresponding to the detection point on the target heating tube. The temperature data of each detection point is used as the ordinate. Coordinate points of the detection points are formed with the second position information as the abscissa and the temperature data as the ordinate. Among them, the change of temperature on the target heating tube is continuous, and the coordinate points of several detection points are connected by a smooth curve to obtain a curve graph, and the bent area of the target heating tube can be reflected by the change of the curve graph.

[0110] Step S602: Obtain a first intersection point and a second intersection point by intersecting a preset temperature line with the curve graph.

[0111] Calculate the tangent slope of the coordinate points corresponding to each detection point on the curve graph. Among all the coordinate points, along the positive direction of the abscissa, mark the coordinate point whose absolute value of the first tangent slope is greater than the preset slope as F1, and mark the coordinate point whose absolute value of the last tangent slope is greater than the preset slope as P1. Mark the coordinate point after F1 as F2, and mark the coordinate point before P1 as P2. Among them, the preset slope is a preset constant, representing the temperature change rate on the target heating pipe. The tangent slope being greater than the preset slope indicates that the temperature change degree of this coordinate point is relatively large. Combining with the curve graph, it can be deduced that starting from this coordinate point, the target heating pipe has a bending situation. Since the temperature change on the target heating pipe is continuous, F1 may be affected by F2, causing the temperature of F1 to increase. Similarly, P1 may be affected by P2, causing the temperature of P1 to increase. Therefore, when determining the length of the second interval, take the midpoint F3 of the ordinates of F1 and F2, take the midpoint P3 of the ordinates of P1 and P2, and since the temperature change on the target heating pipe is continuous, take the average value avg of the midpoint F3 and the midpoint P3. Therefore, the preset temperature line is a horizontal line with the ordinate being the average value avg. By the intersection points of the horizontal line and the curve graph, the first intersection point and the second intersection point can be obtained.

[0112] Step S603: Extract the abscissas of the first intersection point and the second intersection point to obtain a first abscissa and a second abscissa.

[0113] Among them, the ordinate of the first intersection point is the average value avg. The abscissa of the first intersection point can be calculated through the curve graph to obtain the first abscissa. The ordinate of the second intersection point is the average value avg. The abscissa of the second intersection point can be calculated through the curve graph to obtain the second abscissa.

[0114] Step S604: Obtain the length of the second interval by calculating the absolute value of the difference between the first abscissa and the second abscissa.

[0115] By calculating the absolute value of the difference between the first abscissa and the second abscissa, that is, the length mapped to the abscissa from the first intersection point to the second intersection point, the length of the bending region of the target heating pipe, that is, the length of the second interval, can be obtained according to this length.

[0116] By adopting the above technical solution, a scatter plot is formed by the second position information and the temperature data, and the curve graph is obtained by fitting the scatter plot. The change trend of the temperature of the target heating pipe along the length direction can be reflected through the curve graph. By intersecting the preset temperature line with the curve graph to obtain the first intersection point and the second intersection point, the length of the second interval can be obtained more accurately.

[0117] In the following embodiments, during the heating process of several heating tubes, the heating tubes may be damaged, resulting in insufficient total heating of the die holder and uneven heating. To solve this problem, referring to Figure 7 , a temporary heating method is provided, which includes: Step S701: When the current value of the connecting wire is less than the current threshold, mark the heating tube corresponding to the connecting wire as a problematic heating tube.

[0118] Among them, when the current value of the connecting wire is less than the current threshold, it indicates that the circuit corresponding to the connecting wire is open, and the heating tube corresponding to the connecting wire cannot exchange heat with the die holder to provide heat for the die holder, resulting in uneven heating of the die holder. Therefore, mark this heating tube as a problematic heating tube.

[0119] Step S702: Mark the heating tubes among several heating tubes whose distance from the problematic heating tube is within a preset distance range as temporary heating tubes.

[0120] The preset distance range is a preset constant and can be adjusted according to actual needs.

[0121] Exemplarily, with the position of the die holder where the problematic heating tube is located as the center and expanding outward, mark the heating tubes within the specified range as temporary heating tubes. Among them, the specified range can be adjusted according to actual needs. The temporary heating tubes can make up for the lack of heat due to the inability of the problematic heating tube to heat.

[0122] Step S703: Increase the power of the temporary heating tubes in sequence according to a preset order.

[0123] Increase the power of the temporary heating tubes in sequence according to the preset order, so that several temporary heating tubes can alternately increase their power to make up for the heat at the die holder where the object heating tube is located.

[0124] By adopting the above technical solution, when the current value of the connecting wire is less than the current threshold, it indicates that the circuit corresponding to the connecting wire is open, that is, the heating tube corresponding to the connecting wire is not working properly. Mark this heating tube as a problematic heating tube. Then mark the heating tubes among several heating tubes whose distance from the problematic heating tube is within the preset distance range as temporary heating tubes, and by increasing the power of the temporary heating tubes in sequence according to the preset order, it is possible to compensate for the lack of heat due to the inability of the problematic heating tube to work properly, making the overall heat of the die holder stable.

[0125] Referring to Figure 8 , the step of increasing the power of the temporary heating tubes in sequence according to a preset order includes: Step S801: Obtain the distance data from each temporary heating tube to the problematic heating tube.

[0126] The distance data is the straight-line distance from the temporary heating tube to the problematic heating tube. Exemplarily, map the bottom center points of all temporary heating tubes and the problematic heating tube onto the same plane, and calculate the distance from the point corresponding to each temporary heating tube to the point corresponding to the problematic heating tube to obtain the distance data.

[0127] Step S802: Form a distance data set in ascending order according to the distance data.

[0128] The distance data set is a set of data of the straight-line distances from all temporary heating tubes to the problematic heating tube. Exemplarily, if the number of temporary heating tubes is 5, and the distance data from the 5 temporary heating tubes to the problematic heating tube are d1, d2, d3, d4, and d5 respectively, where the magnitude relationship of the 5 distance data is: d3 < d2 < d4 < d5 < d1. Therefore, the distance data set is <d3, d2, d4, d5, d1>.

[0129] Step S803: Determine a preset duration according to the distance data in the distance data set and a preset coefficient.

[0130] The preset coefficient is related to the heat transfer efficiency in the mold base. The preset coefficient η can be calculated according to the heat attenuation model in the mold base. The relationship between the preset coefficient η and the distance data d is: . Where α represents the heat attenuation coefficient of the mold base material. The preset duration t is: . Where t0 is the base duration, indicating the time required to raise the temperature at the mold base where the problematic heating tube is located to the normal temperature value when the distance between the temporary heating tube and the problematic heating tube is 0.

[0131] Step S804: Execute the power increase step. The power increase step includes: increasing the power of the temporary heating tube according to the order of the distance data in the distance data set until the corresponding preset duration is reached.

[0132] Exemplarily, according to the distance data set <d3, d2, d4, d5, d1>, first increase the power of the temporary heating tube corresponding to d3 to reach the preset duration t3, , so as to enable heat compensation at the mold base where the problematic heating tube is located. When the duration of increasing the power of the temporary heating tube corresponding to d3 reaches t3, stop increasing the power of the temporary heating tube corresponding to d3. Then increase the power of the temporary heating tube corresponding to d2 to reach t2, , so as to enable heat compensation at the mold base where the problematic heating tube is located. And so on, until the step of increasing the power of the temporary heating tube corresponding to d1 is completed.

[0133] Step S805: Repeatedly execute the step of increasing power until the mold heating is completed.

[0134] Repeatedly execute step S804, so that heat compensation can be provided to the mold base where the problematic heating pipe is located through the temporary heating pipe to ensure the stability of the heat required by the mold base.

[0135] By adopting the above technical solution, by sequentially increasing the power of the temporary heating pipe to reach the preset duration, heat compensation can be performed on the mold base where the problematic heating pipe is located in the form of heat exchange through the temporary heating pipe, so as to prevent uneven heating of the mold base.

[0137] By adopting the above technical solution, when the heating pipe is working, the current values of the heating pipe are sequentially detected, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value, and by judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to the current value is low, and further indicates that there may be a fault on this circuit, and then the connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating pipe corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating pipe may have a fault. Therefore, the heating pipe is marked as the target heating pipe and the target heating pipe is controlled by a preset control method, so as to provide stable and uniform heat for the mold base.
